3.5.4
TEST – Test
The test is used to activate th e positioner, and you can check
the e
ff
ects of the changes to this parameter group, e.g., by
introducing setpoint changes or setpoint ramps using a
current source.
Normally,
INACTIVE
is shown in the display. To start the test,
press and hold
ENTER
until the countdown from 3 to 0 is
fi
nished. The test is activated . The display shows the control
loop symbol and a
fl
ashing message. The test is automatically
stopped after two minutes and can also be stopped by
pressing any button.
NOTE
It is not possible to start the te st when the safe position is
active (see the
FAIL_POS
parameter on page 31.) Instead,
the message
FAIL_POS
is displayed.
3.5.5
FIND_DEV – Find device
This function is only possible with HART 7 and enables
identi
fi
cation of the a
ff
ected device in the system.
Following activation, the device sends a signal on request
under HART 7. The following signals are available:
— Disable
— One time
— Continuous
3.5.6
EXIT – Return to operating level
With this parameter you can leave the con
fi
guration level. The
positioner returns to the operating level. Here you can either
save data in the non-volatile me mory or discard all previously
made changes (also the changes in other parameter groups).
To leave the con
fi
guration level (with or without saving), press
and hold
ENTER
until the countdown from 3 to 0 is
fi
nished.
The active saving process is indicated by the message
NV_SAVE
. After saving a plausibility check is executed.
If an error occurs during the check or while saving, the data
cannot be saved and an error message is displayed instead
(see Chapter "Error codes" on page 33).
Selection
NV_SAVE
Saves settings in the non-volatile memory.
CANCEL
Discards all changes made since the last
permanent save operation.
